Obtain clamp and contact at inserted link outer wall；When sleeve is constantly close to drill bit bottom, fixture constantly contradicts clamp and extruded towards inserted link,
To cause brill tooth to be fixed on the firmness of fixture.
Further, the height ratio of the length three of the depth of the sleeve, the length of fixture and inserted link is 1:1:1.
Using above-mentioned technical proposal, the height ratio of sleeve, fixture and inserted link three is 1:1:1 causes sleeve to be fixed on
It is more firm on fixture；The inserted link of setting, to increase the intensity of fixture, and inserted link can decompose and bore tooth resistance in use
Power so that brill dental transition adds durable.
Further, the brill tooth is in coniform.
Using above-mentioned technical proposal, setting is in coniform brill tooth, and soil layer is preferably abolished to bore tooth.
In summary, the utility model has the advantages that：Sleeve will be enclosed by two or more stators
Into fixture rotary squeezing, the end of fixture is constantly contradicted with barrel bore, so that being socketed on the brill of fixture
Tooth is difficult to depart from fixture；Clamp is contradicted and slid in inserted link, and when sleeve is constantly close to drill bit bottom, fixture constantly contradicts clamp
Extruded towards inserted link, to cause brill tooth to be fixed on the firmness of fixture.

Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
This specific embodiment is only that it is not to limitation of the present utility model, ability to explanation of the present utility model
Field technique personnel can make the modification of no creative contribution to the present embodiment as needed after this specification is read, but
As long as all protected in right of the present utility model by Patent Law.
Embodiment：A kind of tooth shell of rotary pile-digging machine, as shown in Figure 1, including drill bit 1, the bottom rotatable connection of drill bit 1 have
For closing the drill bit bottom 2 of drill bit 1, five brill teeth 32 are evenly distributed with along the straight flange of drill bit bottom 2, along the arc of drill bit bottom 2
While being evenly distributed with six brill teeth 32, and bore tooth 32 and be each perpendicular to drill bit bottom 2.
As shown in accompanying drawing 2 and accompanying drawing 3, drill bit bottom 2 and bore and be provided with fixture between tooth 32, fixture vertical welding in
Drill bit bottom 2；Fixture is in frustum type, and fixture includes four stators 31, stator 31 by hollow frustum from the top towards
Bottom cross cuts to be formed, and four stators 31 surround tubular to form frustum type so that fixture has certain elasticity.
That bores tooth 32 is welded with sleeve 321 successively and retainer ring 33 towards the end of drill bit bottom 2, and the outer ring of retainer ring 33 is
Regular hexagon；Bore concentric welding between tooth 32 and sleeve 321 and the three of retainer ring 33 so that bore tooth 32 and be arranged on fixture
Shi Gengjia is smooth；It is coniform to bore tooth 32 so that it is more smooth when breaking soil layer to bore tooth 32.
As shown in figures 4 and 5, the outer wall of fixture is provided with spiral lamination 312, and sleeve 321 comes with inner chamber 323, and
Screw thread 322 is provided with the inwall of inner chamber 323；Inner chamber 323 is in frustum type, and the big opening end of inner chamber 323 is less than the big of fixture
Mouth end diameter 0.2mm, the osculum end of inner chamber 323 are less than the osculum end diameter 0.2mm of fixture, to cause sleeve 321 with fixing
When screw thread 322 connects between part, fixture deforms upon, to cause fixture to be fixed in the form of being tensioned in sleeve 321.
Four ends of the stator 31 away from drill bit cover plate 2 are welded with clamp 311, and clamp 311 is towards the fixture center of circle
Set；Bore tooth 32 bottom and be welded with inserted link 3, and its top shape when the diameter of inserted link 3 surrounds frustum type less than four stators 31
Into round-meshed diameter, and formed with interval 313 between four stators 31, to cause four stators 31 by sleeve 321
During rotary squeezing, four stators 31 constantly extrude towards inserted link 3, to cause the brill tooth 32 for being fixed on fixture more firm；
And the depth of inner chamber 323 is consistent with the length of inserted link 3 and the length of fixture, fixture is tightened against completely to bore tooth 32
When, inserted link 3 contacts at rotation bottom surface, to increase the intensity of fixture so that inserted link 3 may help to bore tooth 32 to decompose and use
In resistance so that bore tooth 32 it is more durable.
Operation principle and process：Inserted link 3 is inserted in fixture, people is constantly screwed by instrument by retainer ring 33,
Now, inserted link 3 is close towards the bottom surface of drill bit 1, and four stators 31 constantly shrink so that bores tooth 32 and is secured entirely on fixation
Part.
